WELT-Beaune MACHINE.

Application filed July l5, 1919.

To aZZwiom it may concern:

Be it known that I, AUGUST R. Sononivnr, a citizen of the United States,residing at Somerville, in thecounty of Middlesex and State ofMassachusetts, have invented certain new and useful Improvements inlfVelt- Beating Machines, of which the following is a' specification,reference being had therein to the accompanying drawing.

This invention is a novel welt beating machine, by which I refer to amachine for beatii'ig or analogously reshaping the shoe welt stripattached to a shoe for the purpose of flattening it out' preparatory tosuc-l ceeding operations, such as the attachment of the outsole. Y

Heretofore known welt beatingmachines have proved very inefficient inthe 'proper reshaping ofthe welt strip on the more difiicult shapes ofshoes, and the main object of the present invention vis to overcome thedifficulties heretofore encountered, and to afford a machine in whichthe welt may be expeditiously, efficiently, and non-injuriously attenedparticular objects and advantages of the present improvement will appearin the hereinafter following description of one form or embodiment ofthe invention, or will be apparent to those skilled in the art. To theattainment of the objectsland advantages referred to, the presentinvention consists in the novel'machine, mechanisms, devices,combinations and arrangements herein illustrated, and described.

In the accompanying drawings, lFigure 1 is a side elevation, partly incentral section, of a welt beating machine embodying the presentinvention.

Fig."`2 is a t'opfplan view of the same. Fig. 3 is a right elevation ofthe hammer or 'beating tool.

vil block 12, having its operative or niachined surface 1:3 preferablyhorizontal. A slight recess 1a is Vshown at the inoperative side oftheanvil for a purpose which will bove the anvil is the beater or hammer16, which has the usual down and up inove- The unat one side, andprefments toward and from the anvil. der surface of this tool erablyradially arranged, has an elevation,

rib or ridge 17, adapted at certain times, as

will be explained, to partake of the welt re-`r shaping or flatteningaction. y "lheup and down movements of the beating tooll are effectedby' a vibrating arm 18, fiilcruined at 19, and having at its free end ahead 20, carrying the beating tool. For convenience, the upper portion2l of the head and arm may beremovable, giving access to the interiorparts for assembling, cleaning, etc.

The operating shaft 22 is shown as provided. with the usual fast andloose belt pulleys, and at a point beneath the arm 18 carries aneccentric 23. The eccentricy strap 2l has its web or shanlr extendingupwardly vibrating arm 18. By this the arm, and therefore the beatingtool, are given arapid up and `down vibration of small am blitude, so asto deliver repeated blows flatwise upon the outstanding' F l.

lhe tending up through the head to an exterior point, where a pair oflock nuts 2'? are applied to it to limit or determine the normalposition of the tool in the head. Ay leather washer 28 is placed.beneath the lock` nuts to minimize wear andshoci. Itis desired the tool16 and but not the momentum .of the head ory arm of the machine,andconsequently the `tool and shank are rendered vertically slidable inthe head, being held normally in the relative position shown byv ayields, thusy limiting the beating force, as stated, to that providedbythe momentum or energy of thetool l16 andlits shank 26., IV ith theyield of the spring there will be a slight separation between .the locknuts 27 and the head 20, the washer 28 taking up the shock onrestoration of position.

Broadly, the present invention operates so as to swageor spread the material of the Welt to a greater degree at one edge,namely, the outer This in different Ways, for of the anvil differentialthis is found to rily flattening the might be performedA example,by aslight inclining or hammer, but 1 prefer a spreading action which maywill and set aside at Will, so that the easier parts of the Work may beperformedin the usual manner by a simple, flat hammering action;

To this end 1 apply or form on one-or the other of the tivo members,Vpreferably the hammer'member, a slight elevation, projection beingpositioned, so as to give an accentuated or increased` sivaging' orlspreading action along the outer edge of the Welt. This may take theform of a radially arranged-rib or elevation 17, tapered or graduated indegree or height, as Vindicated in Figs. 1, 3, l and 7. Fig.` 7 showsthe rib 17 in operative relation to the shoe and Welt, and it Will therebe seen that the thicker or higher portion of the rib is applied to theouter edge or periphery of the Welt. By this arrangement during thespreading` or beating action, the periphery of the material is squeezedand swag-ed or spread to a greater degree than the inner part of theWelt, thus materially lengthening the periphery and giving thedifferential spreading action before men- Y tioned, 'so as tosatisfactorily enable the Welt to be properly flattened Withoutresorting to the slashing or slitting, which has sometimes been adoptedheretofore to a similar purpose.

VOrdinarilythe differential spreading action may not be' required, and Ihave rendered the beating tool 16 circularly adjustable, so that at willthe tapered rib 17 may be brought to the inoperative position shown itmay be accommodated within the recess 14 of the anvil, when not inaction, or the operative position shown in Fig. 7. h n

n order to rotarily adjust the beater 16, a bevel gear 30 is fitted to asquared portion of Vthe shank 26. This vfreely permits .thel yieldingmovement mentioned, While the gear is able to rotate the tool betweenits different operative positions. `The bevel gear 30 isengaged by thebevel gear 31, mounted at the upper end of a shaft 32, mounted Withinthe machine arm 18. n'the presentembodiment `I Apropose only two ad] beemployed vat,

The shaft32 at its lower end has abevel gear 39, engaging a bevel gear 40,mounted loosely on the aXle or stud 19 on which the arm is fulcrumed.ecured around the hub of the vbevel Ygear 4Q is a pedal chain 41,presumed to be connected to a convenient pedal.

The operator holds the inverted shoe, as

shown in Fig. 1, and guides it advancingly While the welt travelsbetween the hammer and anvil, and is beaten into fiat condition by arapid succession of repeated blo'vvs.V

What is claimed is: Y 1. A welt beating machine comprising an anvil, abeater vibratable vibratable arm carrying as in Fig. 1, Whereas, when.the beater is rotated so that thepin Fig. 1.
